Detailed Description

The present invention will be described in further detail below with reference to specific embodiments and with reference to the accompanying drawings.

Fig. 1, fig. 2, fig. 3, and fig. 4 show a self-sealing three-way structure provided by the present invention, which includes a dropping funnel 1 and two connecting pipes 2 arranged on the dropping funnel 1; an elastic body 3 is tightly embedded in the dropping funnel 1, a circulation channel 4 for communicating the two connecting pipes 2 is arranged in the elastic body 3, and the circulation channel 4 is provided with a bending part 5; the dropping funnel 1 is also provided with an infusion apparatus interface 6, and the infusion apparatus interface 6 extends along the axial direction of one end of the bending part 5.

When the utility model is used, one connecting pipe 2 is used for connecting with the ureter, and the other connecting pipe 2 is used for connecting the drainage bag; because the elastic body 3 has good sealing performance and plastic deformation, the luer 9 can be conveniently inserted, and after the luer 9 is taken out, the elastic body 3 can automatically close the formed hole by inserting the luer 9, so that the sealing performance of the elastic body 3 is effectively prevented from being influenced after the luer 9 is pulled out from the elastic body 3.

The two connecting pipes 2 are communicated through the flow channel 4, so that the urinary catheter is communicated with the drainage bag when the Ruhr joint 9 is not inserted into the flow channel 4, and therefore urine in the bladder and the flushed solution can be smoothly discharged into the drainage bag through the flow channel 4, and normal liquid drainage is guaranteed.

The infusion apparatus interface 6 is used for guiding the Ruhr connector 9 when being inserted into the flow channel 4, the axial direction of the infusion apparatus interface 6 is the same as the axial direction of one end of the bending part 5, when the Ruhr connector 9 is inserted into the flow channel 4, the central axis of the Ruhr connector 9 and the central axis of one end of the bending part 5 are on the same straight line, and the Ruhr connector 9 can be accurately inserted into the flow channel 4. When the luer 9 is inserted, the insertion end of the luer 9 is close to the outlet end of the flow channel 4, and with the gradual insertion of the luer 9, the distance from the insertion end of the luer 9 to the inlet end of the flow channel 4 is gradually reduced, so that after the luer 9 is inserted into the flow channel 4, the luer 9 seals the outlet end of the flow channel 4, and the sterile solution conveyed through the luer 9 can only enter the urinary duct along the flow channel 4, so that the sterile solution enters the urinary bladder, and the flushing of the urinary bladder is realized. The outlet end of the flow channel 4 is the end of the flow channel 4 connected with the drainage bag, and the outlet end of the flow channel 4 is the end of the flow channel 4 connected with the urinary catheter.

The elastic body 3 is also provided with a splicing seam 7 for connecting the infusion apparatus intubation with the circulation channel 4. When the luer 9 is not inserted into the flow channel 4, the insertion joint 7 is automatically closed because the elastic body 3 has an elastic function, when the luer 9 is inserted into the flow channel 4, the luer 9 pushes the insertion joint 7 open, after the insertion joint 7 is opened, because the elastic body 3 has an elastic function, the edge of the insertion joint 7 covers the outer wall of the luer 9, the periphery of the luer 9 is sealed, and the sterile solution in the effective flow channel 4 leaks through a gap between the outer wall of the luer 9 and the inner wall of the flow channel 4. By arranging the insertion joint 7, when the luer connector 9 is inserted, the insertion joint 7 can guide the luer connector 9, so that the luer connector 9 can be inserted more conveniently, and the luer connector 9 can be effectively prevented from damaging the elastic body 3.
